Name the various ways concrete can be moved and placed.
What will be an ideal response?
Concrete can be moved and placed in a variety of ways. Truck agitators, or non-agitating trucks are commonly used to deliver the fresh concrete. Once on site, the material is moved to points to its point of placement with cranes using concrete buckets, barrows and buggies, chutes, belt conveyors, and concrete pumps (Fig. 8.2). A special placement technique known as shotcrete is placed by pneumatic guns.
